Intel-Nvidia vs Intel-AMD vs AMD-Nvidia: Which one performs best?

Greetings. First of all, a joyous Happy New Year 2019 to you all. I hope that you guys are enjoying your holiday.

Now that we entered 2019, my current HP convertible laptop is nearly 4 to 4.5 years old now and I am seriously thinking of replacing it. I haven't decide on which laptop I want to have right now because I just thought of something.

We see bucket loads of laptop with Intel CPU and Nvidia GPU, but very rarely we see laptops with Intel CPU and AMD GPU, or even AMD CPU with Nvidia GPU. This got me wondering: Out of these three setup, which one would perform best? Let's just assume that I am looking for high-end, flagship laptop/2-in-1/convertible for my car racing sim games and all of my essential Adobe softwares like Lightroom, Muse and Premiere Pro. Touchscreen and pen or stylus support would be an added bonus, if available.

If you're talking just pure performance then Intel continues to be the market leader no matter what combination of hardware you're trying to get in a laptop. If you're looking for performance plus price than you can't really beat AMD. But with the overwhelming majority of laptops being Intel based, it's hard to even start recommending AMD because there's likely an Intel based laptop that can get the job done for roughly the same cost.
